...it´s a problem with Mountain lion
I updated all package from Android SDK manager! and it solved this problem!
Try like this. Delete Android 4.4 (API 19).. and close eclipse and open it again.
and make Android application project (ex: hello) and click the properties.
Today I solved it that way.
update android sdk tools on the "sdk manager" (open as administrator) and update "android tools" on "install new software" ( https://dl-ssl.google.com/android/eclipse/) (v 22.6.2).
worked for me - all the best, you all!
switch to Android-18(or lower) in Graphical Layout (green Android top-right)
